GP6400-10-10-04FP Tompkins JIC-to-O-Ring Gauge Port, -04 Female Pipe Port

The connection geometry on GP6400-10-10-04FP is the key: a JIC connection paired with an O-ring connection, plus a dedicated gauge port specified separately from the main fitting path. The gauge connection is 1/4-18 female pipe. If the mating gauge or test hardware uses the other port style, the corresponding alternate model should be selected instead.

Unlike the JIC-to-JIC families, GP6400 combines JIC and O-ring connection styles on its primary path. At nominal size 10 on both primary connections, this version occupies the mid-range of the family rather than either size extreme.

If the same 10/10 primary sizes are needed with the SAE O-ring gauge-port style, the corresponding alternate part is GP6400-10-10-04FB. Confirm all three connection points against the installation rather than substituting solely on the basis of the GP6400 family name.
